I'm running CyanogenMod 10 on my Nexus 7. As with all other Android devices, for some reason Google thought it cute to check file extensions of incoming Bluetooth file transfers and reject them if they're not one of a handful of extensions.

In other words, a file called file.pem, file.xxx will not transfer via Bluetooth but file.zip or file.jpg will.

Is there something I can do on my rooted device to disable this silly file extension check?
